It is no longer unusual for a spouse or relative to donate a kidney t0 a loved one, but the number of Americans who have given a kidney to a friend, a co-worker or even a complete stranger has risen sharply from 68 in 1994 to 176 in 1998. There are many reasons. First, it's possible to live a normal life with only one kidney. (The remaining kidney enlarges to make up most of the difference.)In addition a kidney from a live donor lasts longer than a kidney taken from someone who has died suddenly. But the biggest change in the past few years is that transplant surgeons have started using 1aparoscopic techniques to remove the donor kidney through a much smaller incision, and this can cut recovery time for the donor from six weeks to four weeks. Just because you do something, however, it doesn't mean you should, Donating a kidney means under- going an operation that carries some risk. You could argue that you may be helping to save a life, but you certainly can't pretend that you're better off with one kidney instead of two. So, what are the risks? “As with any major operation, there is a chance of dying, of reoperation due to bleeding,Of infection,Of vein clots in the legs Or a hernia at the incision,”says Dr.Arthur Matas,director of the renal-transplant program at the university of Minnesota Medical Center in Minneapolis. Even laparoscopy, a relatively new technique for kidney donation, is not risk-free. Doctors estimate that chances of dying from the procedure are about 3 in 10,000. There's no money to be made; selling an organ is illegal. But the recipient's insurance normally covers your operation and immediate aftercare. Your costs can include hotel bills, lost pay during recovery or possible future disability. Although transplant centers must evaluate any potential donor's suitability, it never hurts to have an independent opinion. The most common contraindications(禁忌征候)are heart disease, diabetes and high blood pressure. Never let anyone, not even a close relative, pressure you into giving up an organ—no matter if you're healthy. "There's often the feeling that you're not a good friend, father, mother if you don't do this," says Arthus Caplan, director of the University of Pennsylvania's center for Bioethics. Some transplant centers will invent a "medical problem" on behalf of those who are reluctant to donate but feel they can't say no.

If this happens early enough, the disease can often be treated successfully. According to a survey published last year,21 countries have screening programmes. Nine of them, including Australia, Canada, the US and Spain, screen women under 50. 2.But the medical benefits of screening these younger women are controversial,partly because the radiation brings a small risk of inducing cancer. Also, younger women must be given higher doses of X-rays because their breast tissue is denser. 3.Researchers at the Polytechnic University of Valencia analysed the effect of screening more than 160,000 women at 11 local clinics. After estimating the women's cumulative dose of radiation, they used two models to calculate the number of extra cancers this would cause. 4.The mathematical model recommended by Britain's National Radiological Protection Board(NR- PB)predicted that the screening programme would cause 36 cancers per 100,000 women,18 of them fatal. The model preferred by the UN Scientific Committee on the Effects of Atomic Radiation led to a lower figure of 20 cancers. 5.The researchers argue that the level of radiation-induced cancers is "not very significant" compared to the far larger number of cancers that are discovered and treated. The Valencia programme,they say,detects between 300 and 450 cases of breast cancer in every 100,000 women screened. 6.But they point out that the risk of women contracting cancer from radiation could be reduced by between 40 and 80 percent if screening began at 50 instead of 45,because they would be exposed to less radiation. The results of their study, they suggest, could help "optimize the technique" for breast cancer screening. 7."There is a trade-off between the diagnostic benefits of breast screening and its risks." admits Michael Clark of the NRPB. But he warns that the study should be interpreted with caution."0n the basis of the current data, for every 10 cancers successfully detected and prevented there is a risk of causing one later in life. That's why radiation exposure should be minimized in any screening programme.

第一篇 Pool Watch Swimmers can drown in busy swimming pools when lifeguards fail to notice that they are in trouble. The Royal Society for the Prevention of Accidents says that on average 15 people drown in British pools each year, but many more suffer major injury after getting into difficulties. Now a French company has developed an artificial intelligence system called Poseidon that sounds the alarm when it sees someone in danger of drowning. When a swimmer sinks towards the bottom of the pool, the new system sends an alarm signal to a poolside monitoring station and a lifeguard's pager. In trials at a pool in Ancenis, near Nantes, it saved a life within just a few months, says Alistair McQuade, a spokesman for its maker, Poseidon Technologies. Poseidon keeps watch through a network of underwater and overheard video cameras. Al software analyses the images to work out swimmers' trajectories. To do this reliably, it has to tell the difference between a swimmer and the shadow of someone being east onto the bottom or side of the pool. "The underwater environment is a very dynamic one, with many shadows and reflections dancing around." says McQuade. The software does this by "projecting" a shape in its field of view onto an image of the far wall of the pool. It does the same with an image from another camera viewing the shape from a different angle. If the two projections are in the same position, the shape is identified as a shadow and is ignored. But if they are different, the shape is a swimmer and so the system follows its trajectory. To pick out potential drowning victims, anyone in the water who starts to descend slowly is added to the software's "pre-alert" list, says McQuade. Swimmers who then stay immobile on the pool bottom for 5 seconds or more are considered in danger of drowning. Poseidon double-checks that the image really is of a swimmer, not a shadow, by seeing whether it obscures the pool's floor texture when viewed from over-head. If so, it alerts the lifeguard, showing the swimmer's location on a poolside screen. The first full-scale Poseidon system will be officially opened next week at a pool in High Wycombe. Buckinghamshire. One man who is impressed with the idea is Travor Baylis, inventor of the clockwork radio. Baylis runs a company that installs swimming pools—and he was once an underwater escapologist with a circus. "I say full marks to them if this works and can save lives," he says. But he adds that any local authority spending £30,000-plus on a Poseidon system ought to be investing similar amounts in teaching children to swim.
第二篇 Eat to Live A meager(不足的)diet may give you health and long life, but it's not much fun—and it might not even be necessary. We may be able to hang on to most of that youthful vigor even if we don't start to diet until old age. Stephen Spindler and his colleagues from the University of California at Riverside have found that some of an elderly mouse's liver genes can be made to behave as they did when the mouse was young simply by limiting its food for four weeks. The genetic rejuvenation(恢复活力)won't reverse other damage caused by time for the mouse, but could help its liver metabolize(新陈代谢)drugs or get rid of toxins(毒素). Spindler's team fed three mice a normal diet for their whole lives, and fed another three on half-rations. Three more mice were switched from the normal diet to half-feed for a month when they were 34 months old—equivalent to about 70 human years. The researchers checked the activity of 11,000 genes from the mouse livers, and found that 46 changed with age in the normally fed mice. The changes were associated with things like inflammation and free radical production(自由基)—probably bad news for mouse health. In the mice that had dieted all their lives, 27 of those 46 genes continued to behave like young genes. But the most surprising finding was that the mice that only started dieting in old age also benefited from 70 per cent of these gene changes. "This is the first indication that thee effects kick in pretty quickly," says Huber Warner from the National Institute on Aging near Washington, D. C. No one yet knows if calorie works in people as it does in mice, bus Spindler is hopeful. "There's attracting and tempting evidence out there that it will work," he says. If it does work in people, there might be good reasons for rejuvenating the liver. As we get older, our bodies are less efficient at metabolizing drugs, for example. A brief period of time of dieting, says Spindler, could be enough to make sure a drug is effective. But Spindler isn't sure the trade-off(交换)is worth it. "The mice get less disease, they live longer but they're hungry," he says. "Even seeing what a diet does, it's still hard to go to a restaurant and say: "I can only eat half of that'." Spindler hopes we soon won't need to diet at all. His company, Life Span Genetics in California, is looking for drugs that have the effects of calorie restriction.

第三篇 15 Million Americans Suffer from Social Anxiety Disorder Social anxiety disorder prevents some 15 million Americans from leading normal social and romantic lives, a new survey finds. The disorder leaves many isolated, ashamed and often misdiagnosed. Thirty-six percent of those with social anxiety disorder have symptoms for 10 years or more before seeking help, the Anxiety Disorders Association of America reports. "Social anxiety disorder is when somebody has an intense, persistent and irrational fear of social or performance situations," Jerilyn Ross, the association's president and CEO, said during a teleconference Wednesday. "The condition causes people to avoid common, everyday situations and even other people for fear of being judged or criticized or humiliated or embarrassing themselves," Ross said. Social anxiety disorder can interfere with daily routines and job performance, Ross noted. "It also makes it very difficult for people to develop friends and romantic partnerships," she said. People with this disorder recognize their fear is excessive and irrational, Ross noted. "But they feel powerless to do anything about it," she said. Social anxiety disorder can start in the early teens, Dr. Mark H. Pollack, director of the Center for Anxiety and Traumatic Stress Disorders and a professor of psychiatry at Harvard Medical School, said during the teleconference. "This is a disorder that starts affecting people early on," Pollack said. "The typical age of onset is early adolescence, age 12 or 13, and many individuals report a history of anxiety dating back to earlier childhood." "The disorder also has physical symptoms, including heart palpitations, feelings that their throat will close up, sweating, blushing, faintness, trembling and stammering," Ross said. "Among people with the disorder, 75 percent said the condition affected their ability to do normal activities. In addition, 69 percent said they didn't want people to think they were crazy, and 58 percent said they were embarrassed by their condition, "Ross said. However, when the condition is diagnosed and treated, many reported improvement in their lives. In fact, 59 percent who were receiving treatment said treatment had a positive effect on their ability to have a romantic relationship. In addition, 39 percent who had received treatment said knowing that treatment can be successful aided their decision to get help, Ross noted.

It's about a wacky(古怪的)dad (who's also a scientist) who accidentally(偶然的) shrink's his kids with his homemade miniaturizing (使小型化) invention. Oops! The kids spend the rest of the movie as tiny people who are barely visible while trying to get back to their normal size. 1 It takes place over years and may add up to only one inch or so off of their adult height (maybe a little more, maybe less), and this kind of shrinking can*t be magically reversed, although there are things that can be done to stop it or slow it down. But why does shrinking happen at all? 2 As people get older, they generally lose some muscle and fat from their bodies as part of the natural aging process. Gravity (the force that keeps your feet on the ground) take hold, and the bones in the spine, called vertebrae(椎骨), may break down or degenerate, and start to collapse into one another. 3 . But perhaps the most common reason why some older people shrink is because of osteoporosis (骨质疏松症). Osteoporosis occurs when too much spongy(海绵) bone tissue (which is found inside of most bones) is broken down and not enough new bone material is made. 4 . Bones become smaller and weaker and can easily break if someone with osteoporosis is injured. Older people—especially women, who generally have smaller and lighter bones to begin with—are more likely to develop osteoporosis. As years go by, a person with osteoporosis shrinks a little bit. Did you know that every day you do a shrinking act? You aren't as tall at the end of the day as you are at the beginning. 5 . Don't worry, though. Once you get a good night's rest, your body recovers, and the next morning, you're standing tall again. A. They end up pressing closer together, which makes a person lose a little height and become shorter. B. That's because as the day goes on, water in the disks of the spine gets compressed (squeezed) due to gravity, making you just a tiny bit shorter. C. Over time, bone is said to be lost because it's not being replaced. D. Luckily, there are things that people can do to prevent shrinking. E. For older people, shrinking isn't that dramatic or sudden at all. F. There are a few reasons.

We all know there are times that kids seem to complain 1 a stomachache to get out of chores(零星活儿)or going to school. Don't be so sure that the pain they 2 is all in their minds. We're learning more now about a condition 3 " functional abdominal pain" that is experienced by millions of kids every day. Like many teenagers, Kyle Brust makes it a point to do his homework as 4 as he gets home. Unlike most, Kyle often did this with a terrible stomachache. In fact, the 5 often started while he was at school, but getting help there was getting harder. "Some of my teachers wouldn't let me go, because I'd asked so many times before and they thought I was trying to get out of 6 ," says Kyle. Kyle's mom Marilyn says she couldn't blame the 7 . After all, she'd taken him to the doctor several times herself, and even they couldn't find anything 8 . "You know, you're running the tests and nothing's coming up. So, is it in his head, is he just an extremely stressful child? It's just frustrating 9 we're not finding any answers," says Marilyn. It turns out Kyle was suffering from a condition known 10 functional abdominal pain, that affects as many as one out of every ten kids in this country. Even 11 the cause of the pain may not be obvious, there are real consequences. "It really does hurt, and these kids really do suffer," says Dr, Campo, MD at Nationwide Children's Hospital. To help 12 , Campo is looking into a new approach. He's conducting clinical trials of an antidepressant(抗抑郁药)that changes the way the body handles a chemical called serotonin(血清素). In a preliminary study, Dr. Campo found that in about eight out of ten 13 , the drug normally used to treat emotional pain worked to ease the pain in the 14 .
